Hi Richard, generally these are to be worn as the first layer, and second when you deploy the wind mitt. It would have to be a very thin and tight glove to fit underneath.
Hi Charles, I'd return it if it doesn't fit (note you can adjust the fit by moving the internal harness). But, yes, unfortunately the dual-certified helmets are heavier and less ventilated than the pure climbing helmets. They have to be to meet the specification.
Hi Olga, yes these work with the Pika. The center piece was to help keep Dynafit crampons centered but they kinda dropped support for those.
Hi Coby, yes the Speed and SpeedFit use the 30x39 Radical toe pattern.
Hi Aaron, unfortunately we aren't able to get those separately. However if you e-mail us a photo we can try for a warranty.
